GOP's Future Sits Precariously on Small Cushion of Victory
....Measured as a share of the popular vote, Bush beat Kerry by just 2.9 percentage points: 51% to 48.1%. That's the smallest margin of victory for a reelected president since 1828....

Measured another way, Bush won 53% of the 538 electoral college votes available this year. Of all the chief executives reelected since the 12th Amendment separated the vote for president and vice president — a group that stretches back to Thomas Jefferson in 1804 — only Wilson (at 52%) won a smaller share of the available electoral college votes. In the end, for all his gains, Bush carried just two states that he lost last time.
Another trend explains why all of this might matter to more than just historians: Throughout American history, the reelection of a president has usually been a high-water mark for the president's party. In almost every case, the party that won reelection has lost ground in the next presidential election, both in the popular vote and in the electoral college....

Because his margin was so tight, Bush didn't leave the GOP with enough of a cushion to survive even a fraction of that erosion in four years. Even if the GOP in 2008 matches the smallest electoral college fall-off in the past half century — the 99-vote decline between Reagan in 1984 and George H.W. Bush in 1988 — that would still leave the party well short of a majority.
So Bush needs a second term successful enough to break these historical patterns. That's where his gains at expanding the Republican margins in Congress could become critical. In 2002, Bush became the first president since Franklin D. Roosevelt in 1934 to win House and Senate seats during his first midterm election. This year, he became the first president since Johnson in 1964 to add House and Senate seats while winning another term....
