Republic
Parliamentary vs. Presidential Democracy
Parliamentary Democracy
Strengths:
With this type of government, it’s a little easier to get things passed, as there are fewer steps in the process.
Weaknesses:
On the other hand, there are also some flaws in a parliamentary democracy. The lack of separation of legislative and executive branches means there is no way to measure the prime minister’s power. He may also lack legitimacy, or the quality of being accepted as an authority, because he was not directly chosen as the "leader". The prime minister can be dismissed at any time, which can cause instability in the government.

Presidential Democracy
Strengths:
There are more steps involved in passing a law, which can have positive and negative effects. Because a president is chosen by the people, they will usually be more responsive. Presidents also usually have more legitimacy, or the quality of being accepted as an authority, because he was directly chosen by the people. Some presidents have a history of abusing their power, but the definite separation of branches controls this power abuse. There is also more stability in the government when there are elected officials with fixed terms.
Weaknesses:
On the other hand, it’s almost impossible to remove a president before the end of their term (in the case that he has done something extremely frowned upon or objectionable). Another conflict that can arise, is if the president is from a different party than those in the legislature, they disagree on many matters at hand.
