Amidst all the statistics clamoring for attention during the last six weeks of 24/7 Pennsylvania primary coverage, there's one key number that hasn't gotten the attention it deserves: 306,918. That's the number of new Democrats added to the voter rolls in Pennsylvania between January 1 and the voter registration deadline on March 24. 146,166 first-time voters joined the party and 160,752 switched their registration from Republican or Independent to Democrat. (A mere 39,019 first-time voters joined the Republicans.) The new Democrats have pushed the party's total past the four million mark--a historic first for any party in the state's history. Those voters have the potential to change the results from Pennsylvania dramatically--both tomorrow, and in the general election in November.
At this point, any prediction about which candidate the new Democrats will support in the primary (which is closed; only registered Democrats can participate) is circumstantial. As a group, there's no polling data of their preferences, and newly registered voters aren't identified as such in any statewide poll. But evidence strongly suggests that most of the newly registered voters will support Barack Obama. Both campaigns led efforts to draw in supporters. The Clinton campaign dispatched about 200 volunteers to solicit the state's already registered Democrats, but Obama's campaign was more aggressive in targeting both unregistered Pennsylvanians and the Republican swing voters that he's had success picking off in other primaries.
The highest concentration of newly registered Democrats is in Philadelphia and its surrounding counties--Montgomery, Bucks, Chester, Delaware, Lehigh, and Berks--an area that has become increasingly important in determining the state's elections in recent years. Those counties' registrants make up about half of the 300,000 new Democrats. Though there's no saying for certain just where those voters will go, the region is fertile ground for Obama--Philadelphia is home to a large African American electorate and the fast-growing suburbs, though less diverse, are experiencing a surge in affluent, college-educated voters. "They tend to be fiscally conservative but socially moderate," explained G. Terry Madonna, professor of political science at Franklin and Marshall College. "They're not much enamored of unions, but they're pro-choice and they're relatively tolerant of diversity and they tend to be concerned about taxes." Both Madonna and Jim Hoefler, a professor of political science at Dickinson College, likened the crossover voters to "Rendell Republicans"--the 19,000 Republican voters who switched parties to help Governor Ed Rendell defeat Casey in their 2002 gubernatorial primary battle. And the fact that most of the new Democrats are coming from Philadelphia and the surrounding suburbs offsets the reports from more conservative mid-state counties that voters might be switching as a result of Rush Limbaugh's "Operation Chaos," in which his "Dittoheads" register as Democrats to much with the primary results. In those counties--Limbaugh country--the number of new Democrats is markedly lower.
