The U.S. Senate is expected to vote on the immigration reform plan today. Iowa Senator Tom Harkin, a Democrat, says he’s not sure which way the vote will go. Harkin says if he was forced to bet, he would bet the issue would fail.

The immigration bill was revived after failing to gain support the first time around, and Harkin says failure a second time would end the talk for this year. "I do believe that if this goes down, that’s the end of it, it effectively kills it, yes, until after the next presidential election," Harkin says.

Harkin says he’s leaning against the bill. Harkin says he has some really severe reservations about the bill. "I’ve been willing to let it go to see how we could work it out, to see if things could be handled and stuff," Harkin says, "Boy I tell ya, the more it has gone along, the worse it has gotten." Harkin had said the "status quo" couldn’t continue when it comes to immigration. But, he says this bill is not the answer.

Harkin says this bill is worse than the "status quo." Harkin says they all need to step back as he says they can do a lot of the things they want to do under existing law. Harkin says the immigration proposal is one of the top concerns he hears from Iowans.
