aligning nodes in views grid style
I use the ccs_injector module to add css snippets to fix alignment issues like the one you described.

For example, the css I used to assign even widths on a 4 column grid and to vertically align the content:

td.col-1, td.col-2, td.col-3, td.col-4 {
width: 25%;
vertical-align: top;
text-align: center;
}
