"Because the Democrats already occupy that space, by being very much in the center."
Hahahahaha I love this pretend they put on in an attempt to be "center" but eventually their crazy voters will get angry and start voting green party or whatever lunatic of the day represents them, the Democrats will lurch left in an effort to solidify their base and in so doing reveal their true motives and objectives which will be overwhelmingly rejected by the electorate and we will get a Trump or Trump like Republican in office again
Makes sense, about half are brainwashed leftists morons.
