Today's Gallup and Rasmussen tracking polls, their final national polls before Super Tuesday, show Hillary Clinton and John McCain with the leads going into this crucial day — a sign that both of them are the overall favorites for tonight.

Here are the Dem numbers, compared to yesterday's:

Gallup: Clinton 47% (+0), Obama 42% (-1)

Rasmussen: Clinton 47% (+1), Obama 40% (+0)

On the Republican side, John McCain's support may have dipped a bit in Gallup, but he's still doing more than fine:

Gallup: McCain 41% (-4), Romney 24% (-1), Huckabee 21% (+4)

Rasmussen: McCain 34% (+1), Romney 30% (+0), Huckabee 20% (-2)
