To me, that is the single biggest problem with the current GOP. There are no strong ties that link them together. Can you give me one valid reason why these must happen?
If you want lower taxes, why must you be pro-life?
If you want pro-life, why must you be pro-NRA?
If you are pro-NRA, why must you be anti-gay rights?
If you are anti-gay rights, why must you be for a smaller federal government?
If you are for a smaller federal government, why must you be pro-military?
If you are pro-military, why must you be in favor of lower taxes?
Yet, the GOP essentially requires any politician to link ALL of the topics or be banished. The GOP gets its power, not from a group of united individuals, but instead from an iron fist controlling disparate groups. That tactic worked in the 1990s, but it cannot and will not work forever. The GOP really must fix that problem, or they will eventually fall apart.
The democrats may be weaker (see the health care debacle with strong majorities in house, senate, and presidency), but the personal freedoms they allow their members will eventually win if the GOP doesn't address their discontinuities.
