Ron Johnson You're Running to be a Senator of the Country

Interesting item today from the always interesting Ron Johnson campaign.  He was complaining that some of the stimulus money that Feingold voted for went to a ski resort in Vermont.  Mount Snow for their part said that they actually applied for a government back loan (much like the one Pacur got) and in the end unlike Pacur they turned it down.  I would rather not focus on Mr. Johnson's hypocrisy, but instead what the role of a US Senator is.  He implies with his criticism of Feingold that a US Senator should not vote for anything that fails to benefit Wisconsin.  No, a US Senator represents their State but also the Country.  If a bill is good for the Nation as a whole it should be voted for.  Mr. Johnson would rather see individual States fail.  Had Mount Snow actually gotten stimulus money it would have be spent in other states where snowmaking equipment is manufactured.  It wouldn't of even been spent in Vermont.  On this point of the stimulus the question should be is a role of Government to help the States remain viable?  Wouldn't this come under the US Constitution Article 1 section 8, promote the general welfare.  I know that Mr. Johnson is a Constitution quoting Tea Party Patriot but they all seem to forget article 1 section 8 which delineates the duties of the government.  Who knows exactly who Mr. Johnson intends to represent in Washington but it doesn't really appear to be the State or the Nation.
