<p>There was good news for the Clinton campaign this morning. A <a title="Quinnipiac poll" href="http://www.quinnipiac.edu/x2882.xml?ReleaseID=1142" id="usbj">Quinnipiac poll</a> out Thursday shows Hillary Clinton with &quot;commanding leads&quot; over Barack Obama among likely Democratic primary voters in Ohio and Pennsylvania.<br /><br />

With Obama’s recent string of wins, the Clinton camp is setting up the March 4 votes in Ohio and Texas as a sort of firewall for her campaign, and hoping to pick up more ground with the Pennsylvania primary on April 22.<br /><br />

But some Clinton supporters are worried that the firewall may not be strong enough. Don Fowler, a former chairman of the Democratic National Committee, <a title="endorsed" href="http://www.hillaryclinton.com/news/release/view/?id=4795" id="u8h9">endorsed</a> Clinton in December. While he still stands by her, Fowler told me yesterday that Obama’s momentum is infectious.&quot;If he continues to run the board and win all the states between now and March the 4<sup>th</sup>,&quot; Fowler said, &quot;I’m not sure that Texas and Ohio will hold.&quot;</p>
