Scott Rasmussen is out with two new polls today showing the results of primary challenges to incumbents.  In the first poll, Texas Governor Rick Perry leads Senator Kay Bailey Hutchison 46%-36%, with other candidates accounting for 6% of the vote.  Perry, who became Governor in 2000 by virtue of having been Bush's 1998 running mate, became the longest serving Governor in Texas history in December of 2008, and is seeking a third term.  He was reelected with 39% of the vote in 2006 (in a four-way race).

In New York, Senator Kirsten Gillibrand is in trouble.  She trails Manhattan Congresswoman Carolyn Maloney by 6 points, 27%-33%.  Of course Gillibrand is relatively unknown, with few voters expressing strong opinions of her (or Maloney).  So she's probably not in as bad of shape as your average incumbent drawing 27% in a poll.  As an aside, Maloney was elected to Congress in 1992 by defeating a Republican, Bill Green.  Green was elected to represent the Upper East Side in a 1978 special election, and won re-election as Carter was defeating Reagan by 16 points, Mondale was carrying the district with 61% of the vote, and Dukakis was winning with 66% of the vote.  New York lost three House seats in 1992, two of which came from New York City.  Green had thousands of unfamiliar voters added to his district, and he lost.
