(CNN) – The political momentum is clearly with Barack Obama. He has been impressive. But don’t count Hillary Clinton out yet - she has a formidable political machine and lots of ardent supporters.
Obama has won ten contests in a row - almost all of them by significant margins. But Clinton still has time to come back between now and March 4, when there are major contests in Texas, Ohio, Vermont and Rhode Island. There is no doubt she is facing an uphill struggle, but it would be premature to say it’s over.
I say that as a reporter who has seen Bill and Hillary Clinton bounce back before. During the 1992 Democratic presidential campaign, he was considered politically dead after the Gennifer Flowers scandal erupted. But he overcame that and became “the comeback kid” in New Hampshire.
Her political viability was undermined dramatically when her disastrous health care initiative collapsed after he became president in 1993.
Some pundits began calling him a lame-duck in 1994 when the Democrats lost their majority in the House and Senate. But he came back to defeat Bob Dole in 1996 and won a second term.
Then, there were all the other scandals during his eight years in the White House, including Whitewater, Travelgate, Monica Lewinsky and impeachment. Some suggested he would have to resign. I was CNN’s Senior White House Correspondent then, and I remember those days vividly.
But Bill Clinton survived and even thrived. His job approval rating during his final year in the White House was in the mid-60s. President Bush’s right now is in the low-30s. And Hillary Clinton sailed to victory over Republican congressman Rick Lazio in 2000 in the New York Senate race - even though she had never really lived in New York, and many accused her of being a carpet-bagger.
In short, I think it’s fair to say she’s in serious political trouble right now. But given the Clintons’ history, it would be a mistake to say her quest for the presidency is over. If she manages to win in Texas and Ohio - and that still is possible - she will go on to Pennsylvania on April 22, and this roller coaster political season will continue.
