Iam not from the US and Wikipedia is not really helping in this case:

Is the President of the US allowed to give a pardon to someone who has been sentenced to death somewhere in a State like California, in case the Governor has refused to do so?
How many Pardons can he grant during his presidency?

Article II Section 2 of the US Constitution:

The President shall be Commander in Chief of the Army and Navy of the United States, and of the Militia of the several States, when called into the actual Service of the United States; he may require the Opinion, in writing, of the principal Officer in each of the executive Departments, upon any Subject relating to the Duties of their respective Offices, and he shall have Power to grant Reprieves and Pardons for Offenses against the United States, except in Cases of Impeachment.

There is no limit to the number of pardons a president can grant.

NB: this is the kind of question a quick Google search is great at answering. (E.g., Google something like “Presidential pardon”).

And you’d better choose Texas because California is very unlikely to impose a death penalty.

Here’s a quick reference of all presidential pardons with Franklin Roosevelt topping the list with over 3,000.

Presidents have no limit on pardons nor commutations but they have to tread lightly especially during an election year lest hey hack off their constituents. The crap flying around on the airways as we speak is a classic example.

That’s an intriguing list.  I imagine there are a lot of interesting stories regarding many of those various pardons by various Presidents.
