Brace yourself for a wild ride tomorrow.

New polling data shows that the critical March 4 primaries - with the possible exception of Vermont - appear to be completely up in the air.

Barack Obama now leads 47-44 percent in Texas, as Hillary Clinton gained 1 point overnight in polling conducted by Zogby International. He leads 47-45 percent in Ohio, a shift from Clinton’s 1-point advantage on Sunday.

It’s an amazing turnaround for Barack, but that’s just one polling agency, and those margins are so slim as to be statistically insignificant.

Among seven recent Ohio primary polls, including the newest Zogby poll referenced above, Clinton leads by an average of 5.4 percent.

Among seven recent Texas primary polls, including the Zogby survey referenced above, Obama leads by an average of 1.1 percent. None of the seven give either candidate more than a 4 percent edge, and one is exactly tied.

In other words, all bets are off. Races this close may hinge on undecided voters’ last-minute decisions, as well as the candidates’ ground troops.

Barack Obama and Hillary Clinton are going down to the wire.

The entirely-overlooked New England primaries taking place tomorrow are shaping up differently, despite being two tiny states not very far apart.

A new Brown University poll has Clinton up 5 percent in Rhode Island, while a pair of recent Vermont surveys give Obama a commanding edge.

Polling margins of error are generally 4-5 percent.

No matter how you feel about Hillary Clinton and Barack Obama, it’s nothing short of remarkable that we have elections this late in the primary season that will dictate the remainder of the race, and that three are too close to call.

Your predictions are welcomed!
