"Cuellar emerged victorious in the primary after 419 additional ballots were discovered in two of his stronghold counties, erasing Rodriguez's 145-vote win — but only after two recounts, four court decisions and five months of controversy. He easily beat a Republican and a Libertarian in November.
In Washington, Democrats say they will monitor Cuellar's votes before deciding how warmly to embrace a man who calls himself pro-gun, pro-free trade, anti-abortion and anti-gay marriage."
