If the Presidential election happened today, how would Americans vote? National Journal's Ron Brownstein explains

In one year from today, American go to the polls to elect the next President. In the latest National Journal polls, asked what outcome they would prefer in the 2012 election, 44% of registered voters said they would like to see a Republican elected, while 42% want Obama to win a second term – a split within the survey's margin of error.

Asked if Republicans should retain control of the House, voters tilted slightly in the other direction, with 41% saying yes, and 43% saying they would prefer Democrats to recapture the majority – also within the poll's error margin.

A year away from the election, do voters trust either party? CNN senior political analyst and National Journal's Editorial Director Ron Brownstein breaks down the results with Carol Costello. Brownstein also weighs in on the latest controversy facing 2012 GOP candidate Herman Cain, who faces sexual assault allegations from two former employees.
