However, you still need to reach a majority. Pretending you can win without some moderates/independents defies electoral history.
If you feel that it is necessary to violate those core principles, or not to have any at all, in order to merely win, then go right on ahead. I won't be joining you.
If Palin follows your advice, it would become moot. We'll be watching Obama take his second oath of office in 2013.
Depends on which majority you are talking about.
As you said, conservatives comprise 40 percent of the electorate. So, if only 50 to 60 percent of the electorate shows up to vote in an election, you need a majority of that fifty to sixty percent, or twenty-five to thirty percent of the general electorate, which can be easily filled with high conservative turnout.
Now, you might not even need an overall majority, as was demonstrated in the 2000 elections; all you need to win the presidential election is an electoral college majority, which does not necessarily require an overall majority but only a majority in the States whose electoral college votes you need.
As for winning, the American Revolution was won by a minority. That's something to think about.
