	<description><![CDATA[ "A pollster whose mathematical model has correctly predicted every winner <br>of the White House popular vote since 1988 is banking on a decisive victory <br>for Democrat Barack Obama in November.Emory University political scientist <br>Alan Abramowitz said Wednesday that according to his "time for change" <br>model, Obama would secure 54.3 percent of the popular vote against 45.7 <br>percent for Republican John McCain.That margin would virtually guarantee a <br>crushing victory for the Democrat in the state-by-state electoral college <br>that actually selects the next president, Abramowitz said.He said unknown <br>variables, such as the nation's bitter partisan divide and resistance to <br>Obama's African-American race among some white voters, may result in a <br>slightly smaller popular vote margin for the Democratic nominee.But, "the <br>combination of an unpopular Republican incumbent in the White House, a weak <br>economy and a second-term election make a Democratic victory in November all <br>but certain," he writes in the October issue of the journal "PS: Political <br>Science and Politics.""The good news for Democrats is that 2008, unlike <br>2004, is a time-for-change election - one in which the president's party has <br>controlled the White House for two or more terms," Abramowitz said.His model <br>evaluated Republican President George W. Bush's dismal approval ratings, the <br>change in economic output in the second quarter of the election year, and <br>above all an anti-incumbency mood against the White House party."Regardless <br>of the popularity of the president or the state of the economy, it is simply <br>much more difficult for the president's party to retain its hold on the <br>White House," the pollster said.Abramowitz said his model had correctly <br>forecast the popular vote winner within two percentage points or less in <br>every presidential election since 1988.That includes the 2000 election, when <br>Democrat Al Gore carried the popular vote. But Bush came ahead in the <br>electoral college after his Supreme Court-mandated win in Florida.And the <br>model faces a complication this year with the wild-card presence of two <br>third-party candidates, independent Ralph Nader and Libertarian Bob Barr, on <br>the ballot for the November 4 election." <br><br><br>

	<description><![CDATA[Space Weather News for Sept. 22, 2008<br><a href="http://spaceweather.com" rel="nofollow" class="url" target="_blank">http://spaceweather.com</a><br><br>NEW SUNSPOT: For the first time in months, a significant sunspot is emerging on the sun. <br>It is a fast-growing active region with two dark cores, each larger than Earth.  The <br>magnetic polarity of the sunspot identifies it as a member of new Sunspot Cycle 24. <br>Because the year 2008 has brought so many blank suns, some observers have wondered if we <br>are ever going to climb out of the ongoing deep solar minimum.  Today's new sunspot is an <br>encouraging sign that the 11-year solar cycle is indeed progressing, albeit slowly. <br>Visit <a href="http://spaceweather.com" rel="nofollow" class="url" target="_blank">http://spaceweather.com</a> for sunspot photos and updates.<br><br>SEPTEMBER EQUINOX:  Seasons on Earth change much faster than they do on the sun.  Today, <br>autumn begins in the northern hemisphere and spring in the southern hemisphere when the <br>sun crosses the celestial equator.  The crossing, called the "equinox," takes place at <br>1544 UT (11:44 EDT) on Monday, Sept. 22nd.  Happy equinox!<br>
