When the Whig party refused to deal with the issues of Union and slavery in 1860, they were usurped in their position as a major party by the republicans.
Now that the republican party refuses to deal with the important issues of the day, MOST importantly illegal immigration, who will take their place? Where can a true conservative go to be represented in their beliefs? How do we make a momentum towards what the vast majority of us believe, and if not change the party lines, then at least force the republican party to be serious?
We're suffering from success right now. Why change the MO when we're winning elections? The Democrat party is dying of itself.
