Politically, times are exciting, but also troubling. Tuesday's primary results have made McCain the nominee for the Republican Party, having once and for all beaten Huckabee. But Hillary Clinton's victories in Texas, Ohio and Rhode Island means that it remains a race between Clinton and Obama among the Democrats. The reason this is troubling is that the Democratic Party needs to start mounting effective campaigns against the Republicans, to try to get more undecided and swing voters and to shore up some sort of lead.
