Democrat presidential candidate Sen. Barack Obama, D-Illinois, today unveiled a new $210 billion federal spending plan that he says would create jobs in construction and environmental services.

The Obama proposal would invest money over 10 years in two programs, the largest of which would be a $150 billion effort to create 5 million "green collar" jobs to develop more-environmentally friendly energy sources.

The remaining $60 billion would fund a National Infrastructure Reinvestment Bank to rebuild the nation's highways, bridges, airports and other public facilities. Obama said the construction fund would create nearly 2 million jobs, many of them in construction directly - - a sector hard-hit by the housing sector's correction - - the nation's most severe housing slump in more than 20 years.

Rival Democratic Sen. Hillary Clinton, D-New York, called Obama's effort unoriginal. Neera Tanden, Clinton's policy director, said Obama was offering ideas Clinton proposed months ago. "Voters may ask themselves that if Senator Obama cannot produce his own ideas on the campaign trail, how will he solve new problems as president?" Tanden said in a memo e-mailed to reporters, The Associated Press reported.

Furthermore, the Republican National Committee, which seeks to portray Obama as a tax-and-spend liberal, included Obama's plan on its 'Obama Spend-O-Meter.' The Republicans assert that Obama's announced programs would add $850 billion in federal spending over four years, including health care, education, national service and foreign aid programs, among others. The RNC's web site did not break down the asserted total by year, but economist Steve Affinito told BloggingStocks Wednesday, assuming equal, annual appropriations of $212.5 billion, the total would not be an unreasonable nor an unwarranted outlay, from an economic standpoint, in his interpretation.

"I don't know where the RNC obtained its $850 billion total, but for the sake of argument, even it was $220 billion per year, that's fairly modest, given the services it includes, including universal health insurance," Affinito said. "Also, given the current state of the economy we may find we may need another $150-$200 billion economic stimulus this year, just to keep the economy growing. So in that regard, Sen. Obama's proposal is insinc with the times and a net positive for the U.S. economy."

Sources close to CNN broadcast journalist/commentator Lou Dobbs said he is seriously considering a run for the U.S. presidency in 2008, The Wall Street Journal reported.

Dobbs, who formerly hosted CNN's MoneyLine business news show and currently hosts CNN's Lou Dobbs Tonight has seen both his ratings and his name recognition rise after his work's focus turned away from news reporting and anchoring and toward political and economic commentary.

Dobbs, an independent, displays an ideology and a political world view that many have characterized as a modified hybrid of Ralph Nader and Pat Buchanan -- i.e. populism combined with strong views against free trade (or current trade frameworks) and against illegal immigration.

Dobbs is a frequent critic of both the Democratic and Republican parties, which he argues don't represent the interests of the typical person or the middle class. His show's website describes him as "an independent populist and the leading media advocate for working men and women, their families, our middle class and the American way of life."

Political Analysis: Unless there's a tidal wave of discontent in the American electorate not tallied by pollsters, Dobbs, as a third-party candidate or as an Independent, has virtually no chance of being elected president of the United States. Although his name recognition is rising and he has a positive public image, it's highly unlikely Dobbs could assemble the campaign staff and money required to compete effectively against Democratic and Republican parties' nominees.

However, this is not to say that Dobbs could not broaden the discourse, i.e. "force the discussion of less-publicized issues" during a debate. Dobbs could accomplish this, but it must be emphasized that making points in a debate is a much easier task than receiving enough votes to win the electoral college vote for U.S. president.
