Why the Republicans need to dump Trump

The Argument

The Republicans need to dump Trump and find another nominee if they want the the party to survive. Donald Trump is alienating almost every group of voter and splitting the party with his rants and racist remarks.  In the 1960's Barry Goldwater turned the African-American vote against the Republicans and they have never been able to get the vast majority of that back, Donald Trump could have the same effect on the party this time around by pushing away more African-Americans, Latinos, Muslims, and Women, and splitting the party.

Long Term vs. Short Term

Yes in the short term the party will suffer, they will lose some House and Senate seats and they will loose the White House, but in the long term they will be able to survive and come back.  If they stick with Trump and continue to endorse him they will lose major voting blocks, be painted as the racist and sexist party, and they will lose more and more seats until they cease to exist do to lack of members.

The Problem Today

The problem with today's political parties is they care more about the party than they do about their country, their priorities (Republican and Democrat) go like this:

1. Party
2. Job
3. Constituents
4. Country

When they should have their priorities set like this:

1. Country
2. Constituents
3. Party
4. Job

Learn From the Roman Empire

There needs to be a fundamental shift in the way these politicians think, they need to realize that their arrogance will be their downfall.  There is a reason third parties are rising in popularity, it's because they aren't hated like the two major parties, and if things don't change the two major parties will be a thing of the past in the not to distant future.
I'll admit I'm no fan of either of the two parties, I just hate the Republicans a little more, but I'm reading the writing on the wall, and if things don't change the Republican party will fall, followed by the Democratic party not long after.  And what will happen when that day comes?  Like Emperor Nero when Rome burned, the American people will fiddle while the two parties burn.
