Sen. Hillary Clinton's firewall is burning hotter these days.
The senator from New York has boosted her apparent advantage over Sen. Barack Obama of Illinois in the contest for Pennsylvania's Democrats on April 22: Clinton 51 percent, Obama 35 percent, according to the new results today of a Franklin and Marshall College poll.
This is a doubling of Clinton's edge over Obama in the Keystone State since the last survey of the gauge formerly known as the Keystone Poll. In that Feb. 13-18 survey, Clinton held an edge of 44 to 37 over Obama. Clinton now leads among voters "in virtually every demographic group,'' the folks at Franklin and Marshall report today.
"Obama has the advantage among non-whites and voters in Philadelphia, but he does not yet hold an advantage among young adults — a group he has won by large margins in many early primary states,'' they report. "Male voters are evenly split between Clinton and Obama, and nearly one in seven (13 percent) likely Democratic voters remains undecided.
This may help explain why Clinton is campaigning in Indiana today.
