Exciting, exciting day today -- Nationals tickets go on sale. Oh, and there are some pretty important primaries in Texas, Ohio, Rhode Island and Vermont, too. Please bear with me as I attempt to fill in for the unfill-in-able Reid Wilson.

--In warm and beautiful Washington, D.C. -- where all the action isn't right now -- the House is again holding just a pro forma session, while the Senate continues looking at the Consumer Product Safety Commission bill.

--Here is a rundown of where the Dems stand in the RCP averages in the four primary states: Clinton +1.7 in Texas, Clinton +7.1 in Ohio, Clinton +9.7 in Rhode Island. And in Vermont, where there were not enough polls to calculate an average, Obama led by 24 points in the latest Rasmussen poll.

--Yesterday the Clinton campaign dropped an ad called "True," attacking Obama for not holding oversight hearings on Afghanistan. It includes a clip of Obama admitting to not holding a hearing because he gained the chairmanship at the beginning of the campaign. It seems a bit late in the game for this ad to have much of an effect on today's primaries. Senator John Kerry defended Obama against the ads yesterday, telling reporters in a conference call that Obama jumped into the race with already "more experience in foreign policy than George Bush had, than Ronald Reagan had, and even Bill Clinton."

--Is it just us, or has there been horrible weather on primary days this year? Remember the awful storms blowing through Tennessee and surrounding states on Super Tuesday Feb. 5? The South Carolina GOP primary on Jan. 19 was hit with sleet and snow. The D.C. area had a random ice storm on Potomac Primary day Feb. 12, causing some people 6 hour commutes home from work. And now Ohio.

--The major newspapers are leading with stories detailing the importance of tonight's results for the future of the Democratic primary race. If the polls are correct, we should see incredibly close calls in Texas and Ohio, allowing not much of a net change in pledged delegates. Could this be the end? More on this in the next item.

--The Washington Post included some interesting graphics in today's paper. There are two great visuals in Texas and Ohio showing each candidates areas of strengths. It also included a Post-ABC poll showing two-thirds of Democrats believe if Clinton wins either Texas or Ohio -- not necessarily both -- she should stay in the race.

--Today on the Trail: Obama and Clinton will be in the states they appear to have the best chances of winning. Clinton in Columbus, Ohio, and Obama in San Antonio, Texas. Huckabee will be in Irving, Texas, and McCain will hit the three big Texas cities of San Antonio, Houston and Dallas.
