Josh and I are up in Las Vegas through election day blogging about the campaign, and our coverage has graciously been sponsored by SEIU, whose organizing on the ground in the state we'll be writing about a little later today.

Here are today's numbers:

The composite of these polls has looked remarkably stable over the last two and a half to three weeks since Gallup moved from reporting just numbers on registered voters to reporting numbers on likely voters. During this time period, Barack Obama's level of support has ranged from 49.50 percent to 51.25 percent, while John McCain's level of support has ranged from 43.00 percent to 44.50 percent. In other words, the race has been, and continues to be, stable, with Obama leading by about 6 points and McCain struggling to top 45 percent.

In other polling, CNN's final survey of likely voters finds Obama leading 53 percent to 46 percent, and CBS News polling gives Obama a 54 percent to 41 percent lead -- including an 57 percent to 38 percent edge among those already voting.

We are 2 days out from election day. What are you doing to help enact progressive change in this country?
