Headlines, Feb 20 – Barack Obama continues his momentum as he sweeps states across the country, picking up two more contests. An easy win in his home state of Hawaii and a big win in Wisconsin allows him to slightly expand his narrow lead in delegates.

Obama received overwhelming support in all demographics, except for Hillary Clinton's strongest base - white women over 65.

Clinton downplayed the importance of Wisconsin in recent days, sensing defeat there, instead turning her attention to March 4th primaries of Texas and Ohio.

Pacifica veteran correspondent and Political Science Professor at Cal State University provides some analysis.

"Well for the Clinton campaign it's a warning that Obama has a lot of momentum behind him. It's interesting to notice that the media obsessed over racial and gender issues, only 12 percent of the polls said race was important to them and only 15 percent said gender was important to them."

Hillary Clinton is touting a new do or die speech. It consists of the must know differences between her and Obama.

Republican John McCain also won Wisconsin.
