How to attach column from one file to another file in bash?

How can I attach the first column of a file to another file, using UNIX commands, etc.?

Example:

file1
-----
10 foo
20x bar
30 baz

file2
-----
obama
clinton 
nixon

Result:
-------
10 obama
20x clinton
30 nixon

In my case, file1 and file2 are guaranteed to have the same numbers of lines.

Use cut and paste:

paste -d ' ' <(cut -d ' ' -f 1 file1) file2

Output:

$ paste -d ' ' <(cut -d ' ' -f 1 file1) file2
10 obama
20x clinton 
30 nixon
